Crash when switching from a complete repository to a DVD-based repository: NoSuchGroup: 3d-printing
If you start a Fedora 20 (non-live) install and configure a repository with a complete set of packages - such as the default remote repository configuration, or any full Fedora 20 mirror - then switch to a remote repository which contains only the restricted set of packages on the DVD image - such as a repository which simply is the DVD image, accessed via any protocol, or any other repository somehow generated solely from the DVD package set - the installer will likely crash with a NoSuchGroup: 3d-printing error.
In practice what this means is if you boot the network install image entirely normally, with an active network connection - so that the default remote repository is automatically configured - and then attempt to switch to, say, an NFS or HTTP repository which just contains the DVD ISO image (or has the contents of the DVD ISO image mounted or copied to it), the installer will likely crash.
There are several possible workarounds for this. You can simply set things up so your install repository contains the full package set, not the subset from the DVD image. You can pass in your desired repository configuration with the inst.repo boot parameter or using a kickstart with the repo command - this will cause your chosen repository to be configured straight away, and so avoid the bug. Or you can boot with the askmethod parameter, which has the effect of telling the installer not to try and configure the default remote repository automatically, but to wait for you to enter the Installation Source hub and choose a repository configuration yourself, which again should avoid the bug. You could even boot from the DVD image itself, though that does not seem likely to be a very useful workaround for the majority of cases where you would actually want to install from a separate repository containing only the DVD image file or contents.
Problem with Installation Source spoke when installing from a partially complete kickstart
If you attempt to install Fedora 20 using a partially-complete kickstart - in particular, a kickstart which specifies a package set but no installation source - you will find that the interactive process for setting that option behaves strangely. On the Installation Source spoke, you may not be able to use the default Closest mirror option. If you are affected by this problem, you can manually enter the URL of the Fedora 20 mirror list, and check the This URL refers to a mirror list. box. The URLs for the 64-bit and 32-bit mirror lists are
In custom partitioning, cannot change size of a pre-existing LV after setting a mount point for it and scheduling it to be reformatted
If you use custom partitioning while installing Fedora 20 to a system with a pre-existing LVM LV, assign a mount point to that LV, and set it to be re-formatted, you will no longer be able to request that its size be changed. Any attempts to change the 'Desired Capacity' field and hit 'Update Settings' will result in the size returning to the previous value.
This issue is easy to work around; as long as the volume is not both assigned a mount point and scheduled to be reformatted, you can successfully adjust its size (as long as that adjustment is achievable within the container, of course). So if you run into this problem, simply temporarily undo the mount point assignment and/or 'reformat' check box, make the size change, and then re-apply the mount point and 'reformat'.
In custom partitioning, cannot change size of a pre-existing partition then reset it to initial value
If you use custom partitioning while installing Fedora 20 to a system with one or more pre-existing partitions, then change the target size of any partition and subsequently change your mind and decide you did not want to resize it after all, you will not be able to set it back to precisely its original size (and cancel the resize request). Any attempt to do so will cause the value to change to a previous setting, which can look quite strange.
If you do run into this problem, you can work around it by hitting the 'Reset All' button, which will let you start over from scratch with the storage configuration as it actually exists on the disk(s) prior to Fedora 20 installation beginning.
In custom partitioning, cannot change size of a pre-existing LV multiple times then reset it to initial value
If you use custom partitioning while installing Fedora 20 to a system with one or more pre-existing LVM LVs, and change the target size of an LV more than once during one custom partitioning 'run', you will no longer be able to set it back to precisely its original size (and cancel the resize request). Any attempt to do so will cause the value to change to a previous setting, which can look quite strange.
If you're a bit indecisive about what size you want your LVs to be and run into this problem, you can work around it by hitting the 'Reset All' button, which will let you start over from scratch with the storage configuration as it actually exists on the disk(s) prior to Fedora 20 installation beginning.
If you use the Fedora 20 installer's rescue mode, and enter the interactive shell to try and rescue your installed system, then on exiting the shell it would be expected that you would return to the top-level rescue mode menu, or perhaps that the system would reboot. Instead, you wind up stuck on a screen that says Pane is dead. At this point, your partitions are still mounted, and a hard reset could possibly cause data loss. Do not do a hard shut down or reboot. You can hit ctrl-alt-f2 to get a second shell and run 'reboot', or just hit ctrl-alt-del to trigger a clean reboot.
Upgrade from Fedora 18 with fedup 0.8 fails due to GPG key problems
Version 0.8 of the FedUp upgrader adds checking of GPG keys on packages as a feature. However, this requires that the version of Fedora you are upgrading from have the package signing keys of the version of Fedora you are upgrading to available. At present, the Fedora 20 package signing keys are not correctly available in Fedora 18, so if you try to upgrade from Fedora 18 to Fedora 20 using a 0.8 version of fedup, it will fail at the end of the package download phase with the error message Downloading failed: The GPG keys listed for the "Fedora 20 - x86_64" repository are already installed but they are not correct for this package.
At time of writing, the Fedora 18 repositories do not contain fedup 0.8, but users may find it available through Koji or other means. We will aim to ensure fedup 0.8 is not made available through the Fedora 18 repositories until an update is provided that makes the relevant package signing keys correctly available as well. upgrades using fedup 0.7, as presently available in the Fedora 18 repositories, will not encounter this issue.
If, for some reason, you need to upgrade using fedup 0.8 - for instance, it fixes a bug you are encountering using fedup 0.7 - you can work around this issue by passing the --nogpgcheck parameter to fedup. As the name suggests, this disables the GPG check.
ARM: HDMI output and USB peripherals not working on Beagle Bone Black
Fedora 20 GA has non functional USB/HDMI. At the moment, to use the Beagle Bone Black, you will need a serial console attached to the 6 ping serial header. There's full details [[ http://nullr0ute.com/2013/10/serial-console-options-on-the-beagle-bone-black/ here ]]. The 3.12.5 kernel has full working usb/hdmi/network. It is currently in the kernel-nodebug repository, but there is a low expectation of support or testing of nodebug kernels. The 3.12 kernel should make it to updates-testing soon. Unofficial updated images are planned to be made available by the Fedora ARM team for the convenience of Beagle Bone Black users shortly after the 3.12 kernel lands with the only difference being the 3.12 kernel in the image.
ZIP support in PHP
In Fedora 20, support from ZIP has been dropped from main php package and is now provided in a separate php-pecl-zip package.
If you need zip support, as for any other extension, run
su -c 'yum install php-zip'.
GNOME Shell crashes after creating a keyring without a password
In Fedora 20 with the GNOME desktop, if you attempt to create a new keyring without a password or change the password of your keyring to an empty string (you may do this from the "Passwords and Keys" application, or you may be prompted to create a keyring password the first time GNOME attempts to store some kind of key), the GNOME shell will crash. The workaround for this is to always use a password on your keyring.
An updated clutter package has been submitted to the updates-testing repository for testing. Users experiencing this problem are encouraged to test this update and report to Bodhi whether it solves the problem. However, note that one tester has reported that the update causes graphical corruption issues on an Intel video adapter. To test the update, run this command:
su -c 'yum --enablerepo=updates-testing update --advisory=FEDORA-2013-22280'
Attempting to launch the application Panorama Stitcher from the KDE menus in Fedora 20 will result in it crashing. This application is only present on the menus by default if you install from DVD, not if you install from the KDE live image. The panorama function is really one of the many Kipi image manipulation plugins for KDE, and is usually expected to be accessed from a Kipi-enabled graphics manipulation application; its presence in the menus is only a convenience. If you do want to invoke the panorama function directly, you can call it with some image files as arguments -
panoramagui image.jpg image2.jpg image3.jpg ... - and it will run successfully.
su -c 'yum --enablerepo=updates-testing update --advisory=FEDORA-2013-23252'
Testing has indicated that, in Fedora 20, it is not possible to browse SMB/CIFS shared resources - i.e. Windows or Samba file or device shares - with the default FirewallD firewall enabled, even if you enable the 'samba-client' firewalld service. By comparison, in Fedora 19, browsing appears to work even without needing to enable that service. The issue is not specific to a particular desktop or file manager utility, it seems to be an issue in the firewalling layer. You can connect to a share by entering the path explicitly, and shares that are advertised via zeroconf/Bonjour may show up when you browse.
Besides using zeroconf or simply directly entering share addresses, there are two possible workarounds for the bug, but neither is without consequences. You can simply disable the firewall (from the firewall configuration tool, or with
su -c 'systemctl stop firewalld.service'), or place the relevant network interface in the 'trusted' firewall zone (which allows all traffic to and from that interface, so is more or less identical in effect to disabling the firewall) - you can do this from your desktop's network configuration utility. Either of these approaches, obviously, results in your losing the security benefits of the firewall. Alternatively, you can configure a custom firewalld rule to accept all from source port 137/udp; this is less drastic than disabling the firewall entirely, but still possibly constitutes a slight lowering of protection.
If you do use a workaround to enable browsing, we would suggest doing so only long enough to discover the shares you wish to configure, then setting up some sort of permanent configuration / bookmark for them, so you no longer need the browsing functionality and can drop the workaround.
We are currently investigating and attempting to come up with a correct resolution for this problem.
libvirt guests are killed on host shutdown
When hosting virtual guests via libvirt in recent Fedora releases it is intended that, if you shut the host down with the guests still running, they will be suspended and then resumed when you boot the host up again. This does not currently work in Fedora 20. If you shut the host down with guests running, they will simply be uncleanly shut down (the processes are killed).
We are currently investigating to try and find a fix for this issue. In the mean time, if your virtual guests are of any value to you, please shut them down cleanly before shutting down the host. We apologize for any inconvenience this may cause.
